Is it normal to sleep 16-18 hrs a day after an insomnia phase?
For the past couple days, I have gotten at least 16-18 hours of sleep each. It's stange, because I'm normally an insomniac, but today, I've been asleep for the majority of the day and I still feel like falling asleep. Same thing happened yesterday.
Is it possible that insomnia put me in so much "sleep debt" that I've needed to sleep this much?
Another thing: I recently switched antidepressants (Effexor to Cymbalta), so that may have something to do with it, but withdrawal from Effexor isn't supposed to cause hypersomnia.
